SUPPORT-FOR TELEGRAPH LINE-WIBES AND THE LIKE.

To all whom it may coiwem:

Be it known that 1, JAMES F. WILSON, a

certain new and useful Im rovements in- Su ports for Telegraph Li'neuse and the I L e, of which the following is a specificawill .tion.

'ping of the wires will be the sa several views.

invention relates to supports for telehone line wires, electric light the like, and the object is to eflicient brackets y graph and tele line wires, an

rovide simple and highly or holdin such wires securely in place and devices w ch are easily and uickly mstalled and devices which will hol the, wires securely from post to post so that the wires will not drop to the ground exce t possibly between the posts where the bre occurs in a wire and to hold the wires in case ofexpansion of the wires that the only dropbetween osts. Other objects and a vantages to provide devices that will/ endure indefinitely as there will be nothing to decay. The devices will be fully-explained in the following descri tion and the invention will be more artic rl pointed out in the claims. Re erence is ad to the accompanyingdrawings which form a part of @1118. apphcation. 4

Similar characters of reference are used to indicate the same parts two A post 1 of ordinary type is shown' broken away at the bottom. The cross bar 3 has an ofi-set to receive the post 1 and the bracket will be gained into the post in the usual manner so that the weightwill be directly on the post. The cross ar or main bracket bar 3is preferablymade of metal. Braces 4 are attached to the post 1 and to the bar 8 for making the bar 3 rigid. The wires 5 are clamped secur 1y against longitudinal movement. Insulation blocks 6 are provided and each insulation blockG consists of two parts, the planes forming the meeting faces of the two parts being vertically arranged so that Specification 01' Letters Patent.

ongitudinally in the clamps 7. The clamps 7 .are locked securely in the cross-bar 3 wedge shaped keys 10 driven through hori-- zontal recesses in the bar 3, the horizontal openings intersecting partly thevertical recesses. One arm of the clamp 7 has a cut-out 11 to receive the key 10 so that the clamp will be securely locked againstvertical movement in the bracket bar. The key 10 may be serrated or notched on one edge, as at 12, to

form slight shoulders on the key to prevent backward movement of -the key through the bar 3. The shoulders will catch against the angle formed by the recess and the face of the bar and thus prevent backward movement of the key after it is once' driven through the bar 3. o

There may be-as many bars 3 on a post as may be necessary and there may be as many clamps in each bar as may be necessary'or ex- 'pedient. portions, and construct1on of the various parts may be made without departing from my invention.

What I claim, is,

,1. A support for telegraph line wires and the like comprisin a crossar having vertical openings and orizontal openings intercepting said openings, clamps secured in said openings, flanged insulation in two parts carried b said clamps and clamped on the line wires y said clam s, and means in said horizontal openin s or locking said clamps against vertica movement' 2. A support for telegraph line wires and the like comprising a cross-bar having vertical openingstherethrough, line on aging members, each consisting of a bloc, of insulation in two parts for receiving awire and having faces meeting in a vertical plane,

a clamp bent about the parts of said insula- Various changes in the sizes, protion and having arms sprung together and inserted in one of said openings and clamping said insulation on the wire, and a key for locking the clamp in its opening.

3. Asupport for telegraph line wires and the like comprising a cross-bar having vertical openings therethrough and horizontal openings therethrough intercepting said vvertical openings, line engaging members,

each consisting of an insulation block in two parts, a clamp bent about said insulation and having arms sprung together, forcing said insulation on a Wire and inserted through one of sald vertlcal openlngs, one

of said arms having a recess in the outside, 15

and a Wedge-shaped key for locking said clamp in said opening inserted through one of said horizontal openings, engaging the recess in said'arm.
